Am I the only one who thinks brooming a slab right after the bleed water comes up is a mistake
A finisher named Ray at a pour in Bakersfield swore by brooming at 45 minutes on a 90 degree day, and I watched that finish peel off the following spring because he trapped water under the crust, so I wait until the sheen is gone and thumbprint holds, but maybe I am just slow, how do you all time it?
